About error code 4352

Kova

Hello.

In order to connect multiple units on the previous question page (https://devzone.nordicsemi.com/f/nordic-q-a/51970/implementing-multilinks-on-multiroll-programs), we were able to specify the array.
However, when I implemented the program, I got the following error:

peer_manager_handler: Connection security failed: role: Peripheral, conn_handle: 0x0, procedure: Bonding, error: 4352
Disconnected, reason 8

What are the possible causes for this “4352”?Thank you.

The environment is as follows.
SoftDevice: S132
IDE: SES
BLE Device: NRF52832
SDK version: 15.30
peripheral project: ble_peripheral⇒ble_app_hrs
multirole project: experimental⇒ble_app_multirole_lesc

    Have you tried looking it up?

    Find the point at which that error message is generated, and find where the error code comes from - you should be able to find a definition from there ...

    Hi awneil.
    Sorry for the late reply.
    The question error is a peripheral device with no code changes. So, I thought about the multi-roll device that was changed.
    The evt_id when the operation was stopped on the multi-roll side was in one of the following two states.

    evt_id: 48⇒BLE_GATTC_EVT_PRIM_SRVC_DISC_RSP
    evt_id: 24⇒BLE_GAP_EVT_LESC_DHKEY_REQUEST

    Also, when I checked the situation on the debug screen, I found that it stopped with the following exception.

    Exception name: BusFault
    Assembly code when an exception occurs: ldr r3, [pc, # 4]

    As a result of examining "BusFault", I want to see the fault related to address and memory. What can be considered is an error when referring to the memory of an array that is specified more than once. Please let me know if you have any advice.
